Alright, this time on time and not weeks behind the official release like the last update of Postfix. Wietse released a minor bug-fix which solves some problems in the SMTP client. The bug-fixes include:
- A remote SMTP client TLS certificate with an unparsable canonical
name triggered a panic error in the Postfix SMTP server (attempt
to allocate zero-length memory) while sending a request to an
SMTPD policy server.
- On backup MX servers where the queue file system is mounted with
“atime” (file read/execute access time) updates disabled, the
flush daemon would trigger mail delivery attempts once every 1000
seconds, thus rendering the maximal_backoff_time setting useless
for backup MX service.
This update has been tested on my test server and my production server is using this latest release as well for a few hours now without a problem.
By the way as a sidenote, I’ve ordered my Leopard box in the online Apple store. I need to prepare my test server for the upgrade!
